液氢储存具有单位体积储氢密度高、长距离输送成本低等优势。但液氢储存是将氢气冷却到-253 ℃进行液化后储存在绝热容器中，故对储存容器的低温绝热性能要求极高。围绕液氢储存被动绝热和主动绝热技术，通过文献调研的方式回顾了当前液氢储存低温绝热技术的研究进展，介绍了不同绝热技术的原理，比较了不同绝热技术的适用范围，分析了目前不同绝热技术中存在的瓶颈问题和不足之处，总结了各绝热技术未来的发展趋势。为液氢储存低温绝热技术的发展提供参考。

Liquid hydrogen storage has the advantages of high storage density per unit volume, low cost for long-distance transportation, etc. However, in the liquid hydrogen storage, the hydrogen gas is liquefied at -253 ℃ and then is stored in the cryogenic insulation vessel, which requires extremely high cryogenic insulation performance. The passive and active thermal insulation technologies for liquid hydrogen storage were focused on, and the current research progress of cryogenic insulation technology for liquid hydrogen storage was reviewed through literature. The principles of different insulation technologies were introduced and the application scopes of different insulation technologies were compared. Meanwhile, the bottleneck problems and shortcomings of the current insulation technologies were analyzed in derail, and the future development trends of each insulation technology were summarized. This study can provide valuable reference for the development of cryogenic insulation technology for liquid hydrogen storage.
